Hi There,well this is a lot of surgery !if you get liposuction on your flanks + a full tummy tuck, it is already a good 3-4 h.I usually do not like to recommend lengthy procedures, since us women have more risks of blood clots ( Deep vein thrombosis ) after 4 h under anesthesia and especially after abdominoplasty ( tummy tuck ) on top of more problems with healing, infection, bad scarring.plus the recovery is hefty; for a tummy tuck, you will go home with drains, and no sports, no lifting for 6 weeks.so add a breast reduction procedure, then you may be in pain in your abdomen + breast...you should discuss all this with your surgeon, who is a board certified plastic surgeon.you should consider splitting the procedures, and start with the one problem area which bothers you the most.these surgeries are to make you look nice, not to have problems.good luck,Florence Mussat
